All the alleged stalking claims about Mark came from Linda, with no evidence shown to support her claims except that Mark had admitted to friends that he had gone through Linda's garbage bins looking for evidence that SHE was stalking him and messing with him by putting drugs in his car, etc. And yes I too thought on the video that the figure of 'Mark' was actually Oakes because they looked a bit alike. The figure certainly moved like a younger man. Mark had moved on with a really nice new girlfriend and I think Linda thought he should be suffering and missing her, not thriving. She convinced pathetic-liar Oates to kill him. Some things I never heard if the police followed up on: did they check Oates' bank account for a sudden large amount of money, as he told his ex that he had done the 'job' for a rich man'? Did they ask his daughter if it was true he trained her to shoot and defend herself from the so-called 'domestic terrorist' Mark Stover? Sidenote: Did Linda hang around for long with Oates's family after he went to jail? I bet she bailed after a pretense of caring, or else bought them off. I see her father got some payback though, contracting Alzheimer's and dying in 2018.
